I accidentally purchased a fake CNHG901 HG-X11 Chain for my Shimano 2x11 M700 Groupset because my original chain already had 0.75 wear. I was naive and stupid to think that I'd actually get a legitimate chain for the amount of money that I was paying. My question is, since the option of getting a refund is already out, is it actually safe for me to use this chain on my bike or am I better off not using it at all.
Additional info: I found out the chain was not authentic through this video:where I found many differences between my chain and the one in the vid. Mine had engravings on both sides and not just one, it came with a quick link but not an instruction manual like in the video, and cost about 50% the price of a legit chain.
(The chain in the YT video is not my chain, the video is an actual unboxing of a legitimate shimano chain, I used the video to compare the chain I got and the chain in the video.)
